Fall Watch

The fall equinox is just three weeks away, but I've been sensing the change since mid-August. The first thing I noticed was the hint of autumnal crispness in the early morning air, as Bobo the Husky and I set out for our morning walks. It was a topic of conversation with my fellow dog walkers. Then I started to notice that it stays darker longer in the morning, and gets darker earlier in the evening. Now I'm noticing that the afternoon chill comes on stronger and earlier in late afternoon, prompting me to reach for a sweater to ward off the chill.

With our Mediterranean climate, the hot summer dry weather is still to come. The Bay Area can expect several significant heat spells between now and the end of October, relieved by stretches of our typical temperate weather. Fall fires are a constant worry, bringing danger and the smell of smoke on the air. Hopefully the rainy season will start in early November.


Roasted vegetables are perfect for fall eating

What to eat is a conundrum. During the heat spells, we still enjoy barbeque, green salads, corn on the cob, and cold summer salads. But on the cooler days, we start craving soups, stews, roasted vegetables, and baked goods.

Mushroom Hunter: Dr. Dennis E. Desjardin

Dennis Edmund Desjardin (1950-current) is an American mycologist who has been called the "Mushroom Guru of the West Coast". He was born in Crescent City, California and started his life's work at the age of three, collecting mushrooms with his grandparents. He attended San Jose State University for a time but dropped out to play jazz professionally.

A decade later, he attended San Francisco State University and graduated in 1983 with a B.S. in botany, and in 1985 with an M.A in ecology and systematic biology. His M.A. thesis (The marasmioid fungi of California) was supervised by Harry D. Thiers (see Mushroom Hunter: Dr. H. D. Thiers). Desjardin attended the University of Tennessee and graduated in 1989 with a Ph.D. in mycology. His Ph.D. thesis (The genus Marasmius from the southern Appalachian Mountains) was supervised by Ronald H. Petersen.

Desjardin worked as an assistant professor at a small liberal arts college in Ohio, and then worked his way up to a full professorship at San Francisco State University, where he worked until his retirement. He researched mycology in California and around the world, funded by numerous National Science Foundation grants. He conducted field studies and documented fungal diversity and the ethnomycology of indigenous cultures. He is the author or coauthor of over 150 scientific publications. He was appointed the director of SFSU's Harry D. Thiers Herbarium, and served as an associate editor for Fungal Diversity and Mycologia.

Dr. Desjardin spent 40 years documenting California's mushrooms, and coauthored California Mushrooms: The Comprehensive Identification Guide. He also researched ecology and the biogeography of fungal species associated with tropical and island habitats, bioluminescent fungi, and fungal systematics. He coauthored "Mushrooms of Hawai'i: An Identification Guide".  Desjardin discovered or co-discovered more than 300 fungal species, including species of luminescent mushrooms. Several mushrooms are named after him, including Agaricus desjardinii, Marasmius desjardinii, and Arcangeliella desjardinii. He retired from SFSU in 2021 and left academia to start a new career at Sempera as Chief Mycologist.

I was interested to learn more about Dr. Desjardin because of his specialization in Californian mushrooms, and his interest in fungi around the world. I especially enjoyed reading about the naming of the SpongeBob SquarePants mushroom (Spongiforma squarepantsii). It's always a joy to see scientists having some fun! I also appreciated hearing that Dr. Thiers had named Gastrolactarius desjardinii to honor his colleague/protege.

Note: mushrooms are  renamed and reclassified continually as new information is discovered.

Field Notes for August 2026

Welcome back to Field Notes!


August 1, 2026

Bobo Chronicles: Outing to Dracena Quarry Park. Bobo the Husky loves to explore new places. Mari gave me a tip about nearby Dracena Quarry Park. Rick, Bobo, and I visited this neighborhood park, which is nestled in a small canyon under a stand of redwood trees. We enjoyed a stroll in the deep shade, and a drink of cool water on one of the park benches. Small parks are one of the many things that I enjoy about living in the East Bay. Thanks, Mari!

Look at This Slime Mold! My brother Dave sent me a picture of this glorious lemon-yellow slime mold. He was walking on North Douglas Island, near Juneau, Alaska, and checking out the beaver ponds. I haven't identified it. Could it be a Fuligo species? If so, Wikipedia provides this information:

Fuligo is a widespread genus of plasmodial slime mold in the family Physaraceae. These organisms are protozoans rather than fungi, but for historical reasons are sometimes treated as part of mycology.

Possibly, Fuligo septica, (also known as the dog vomit slime mold or scrambled egg slime). Fascinating!

Happy Birthday to Rick! My wonderful husband just turned another year older. I think he is aghast at this bigger number, but he is just as hilarious, interesting, capable and cute as ever!

Field Trip to the Ferry Building.  Mari, Gaymond and I skipped the Over-the-Hills Gang hike this week and went rouge! It was such a beautiful day that we decided to take the ferry from Jack London Square to the Ferry Building instead. It's always great to get out on the water. We had some great views of the Port of Oakland, the container cranes, the underside of the Bay Bridge, and a whole variety of ships and crafts out on the water. Once we docked, we explored the Ferry Building and the Farmer's Market, and scoped out eateries for lunch.

We walked along the Embarcadero for a ways and explored some of the piers. There has been a lot of development since I last visited the area. I almost had a feeling that I was walking along some of the waterways in Europe!

We returned to the Ferry Building and made our purchases at the Farmer's Market and Ferry Terminal, and ate outside in the sun (dim sum and empanadas). I picked up some empanadas to take home for the guys and Bobo the Husky, and we took the 1:05 ferry home. What a wonderful experience!

Visit to Far West Fungi in the Ferry Building. While at the Ferry Building, I made a point of stopping in at Far West Fungi. They have an amazing selection of seasonal fresh mushrooms, bulk dehydrated mushrooms, and smaller packages of dried mushrooms. They also sell fun fungi-related merchandise, such as mugs, dish towels, and mushroom-growing kits.

I purchased packages of dehydrated Wood Ear, Porcini, and Morel mushrooms for some future cooking projects. Stay tuned!

Summer Read. I've been working through my summer reading list, and just finished "Garden of Lamentations" by Deborah Crombie (William Morrow, 2017). This is the seventeenth novel in the Duncan Kincaid/Gemma James series set in London. In this one, a crime takes place in one of its gated neighborhood gardens. Crombie  provides "A Short History of London Squares" in the back matter, which is all about the "network of enclosed garden squares winding through the city (of London) like interconnected necklaces of green".  Illustrator Laura Maestro provides the endpaper map for the story, which is charming and adds dimension to the mystery. Together they make the story all the more engaging (see both the book and map here)!

Happy Birthday to Aunt Char! My wonderful aunt is turning (a bigger number) and we plan to celebrate at her open house tomorrow. I really enjoyed spending time with her and my mom in Juneau, Alaska this year (in both winter and summer), and love going places with her here in the Bay Area (or wherever we travel). I'm grateful that she lives nearby and has such a wonderful outlook on life. My cousins will be here for the birthday bash (Jen from Idaho and Chris from Arizona), so that will be the icing on the cake!

OTHG Hike to Marina Bay. Mari, Gaymond and I met up with the Over-the-Hills Gang hike at the Marina Bay in Richmond for the latest 55+ group hike. Marina Bay is located in the Richmond Inner Harbor, the former location of the World War II-era Kaiser Shipyards. We hiked the area a year ago, and enjoyed great views of the bay, wildlife in Meeker Slough, and proximity to multiple destinations (Marina Bay Park, Marina Bay Yacht Harbor and Yacht Club, the Rosie the Riveter Memorial, and a residential community along the shore). 


You Are Here - with so many great options nearby!

The sky was overcast and the temperature chilly, but we still had great views in all directions. The slough is a popular spot for birds to gather, so we had a chance to see pelicans, herons, ducks, geese, and more.

Anthony Fisher led our bay-side hike, and provided information about flora and fauna and delicious cookies at the half-way point. Mari, Gaymond, and I finished the hike with delicious food and conversation at the nearby Anh Restaurant & Bar. These hikes are so much fun - the pace is perfect and the company is excellent. Check the website to learn more about upcoming events offered by the East Bay Regional Park District.

Flora and Fauna at Marina Bay. While at Marina Bay, we saw lots of heron, ducks, Canadian geese, and lots of gulls and shore birds. We also say a Black Oystercatcher by the shore.

Cooking with Mushrooms - Wood Ear. I purchased dehydrated Wood Ear mushrooms from Far West Fungi on our trip to the Ferry Building (see the August 11 entry above), and added them to a buckwheat noodle and dashi soup bowl. Wood Ear (Auricularia auricula-judae) are called jelly fungus because of their texture, but others are somewhat rubbery and gelatinous. The species grows throughout Europe and North America and is cultivated in China and East Asia. Far West Fungi grows them at their facility in Moss Landing, California.


Dehydrated Wood Ear Mushrooms


This was my first experience with Wood Ears, and I was struck with how much the reconstituted mushrooms resembled ears! They have a wonderful, crunchy texture, but not much flavor (they are typically incorporated in hot-and-sour soup, or used as a main ingredient in salads with a strong dressing). They were a little bland in my soup bowl, but did have an interesting crunch.

Landscape Maintenance. I spent a lot of time in the landscape cutting back our many grass clumps in response to the Fire Prevention inspection in July. The inspector felt the long, dry grasses could pose a fire risk. This gave me the opportunity to learn how to trim the grasses, and we are now back in compliance and fire safe. In between trimming up grasses, our family has been enjoying lots of outdoor living. We can be found out on the patio most afternoons, whether in the midst of a heat spell, or on cool, foggy days. Here are few other maintenance tasks for August:

✘ Weed the garden paths and beds (ongoing task). Note: as part of the grass clump clean up, I removed quite a few grasses that were starting to encroach on the paths. This widened the paths back to their original dimensions.

✘ Sweep debris from surfaces throughout the yard. 

✘ Clean up the stone walkway from the street to the house. Remove the weeds that pop up between the pavers, and that sneak into the planting beds and nearby cracks in the street (some people recommend spraying with vinegar to desiccate the leaves, although it may not kill the roots). Cut back the ground covers that spill over onto the pavers, and the grasses that spill over the path.

✘ Likewise, clean up the streetside, easement area for weeds and trash. There are some beautiful native plants in this area; prune or thin as needed to show them to their advantage. Add mulch or wood chips as needed. Note: I pulled a number of tall dandelion weeds from this area, but overall it looks like a lovely tapestry of plants.

🚫 Arrange for a pruning estimate to trim the oak. Note: we had the oak tree pruned last fall, and it still looks good – no branches overhanging the house or traffic. It will probably be good for another five years unless something changes. The rest of the trees and shrubs look good for now.
